4 Claims.

My inventionrelates to the construction of metal barrels, particularlythose comprising an inner fluid container and an outer reinforcing andinsulating shell.

One object of my invention is to provide an improvement upon the metalbarrel construction disclosed in the co-pending application of- Clarence W. Avery, Serial No. 673,762, filed May 31, 1933, and theco-pending application of James Vehko, Serial No. 684,325, filed August9, 1933, the said Avery and Vehko applications each disclose aconstruction in which the inner container of the barrel is composed oftwo like cup or pot shaped parts joined together by outwardly extendingflanges. at their open ends, and the outer shell is likewise composed.of twolike cup or pot shaped parts, the edges of which around the openends are joined together and to the inner container at the outwardlyextending flanges provided upon the inner container.

My improvement comprises generally the provision of irregular flangesabout the open ends of the inner container, that is the flanges extendoutwardly a greater distance at spaced points. providing outwardlyextending spaced lugs to which the edges of the outer shell parts may besecured for the purpose of securing the outer shell to the innercontainer, and providing spaces between these outwardly extending lugsin which heat insulating material may be placed, or which may beleft asdead air space, to prevent heat conduction from the inner container, tothe outer shell and vice versa.

My improved construction provides a more completely insulated barrelthan that disclosed in the above mentioned co-pending applications ofClarence "W. Avery and James Vehko.

For a better understanding of the invention, reference may now be had tothe accompanying drawing, in which:

Figure 1 is a vertical cross-sectional view of a metal barrel embodyingmy invention.

Fig. 2 is a horizontal cross-sectional view taken on line 2--2 of Fig.1.

Fig. 3 is a sectional view taken on line 3-4 of Fig. 2.

Fig. 4 is a sectional view taken on line 4-4 of Fig. 2.

Fig. 5 is a sectional view illustrating a modification of the jointillustrated in Figs. 3 and 4 between the parts of the outer shell andthe inner container.

Fig.6 is a fragmentary elevational view of the central portion of thebarrel showing the two parts of the inner container assembled togetherand the two parts of the outer shell separated to.

better illustrate my improved construction.

The barrel comprises generally an inner container l composed of two likeparts 2 and 3 which are generally pot shaped having closed ends and 5having. outwardly extending flanges 4 formed around their open ends. Theflanges i of one part are adapted to mate with like flanges 4 on theother part and to be secured to each other by welding or other similarmeans to provide a o fluid tight joint around the centralcircumferential part of the inner container. The outer shell is composedof two like parts 5 and 6 also generally pot shaped and provided withoffset portions 11 which provide reinforcement and 1e chime portions 8around their closed ends. A tap bushing ii is provided at the top of thebarrel and is secured in registering openings of both the innercontainer and outer shell, and a hung bushing it is positioned in thecentral part of the barrel and is likewise secured to both the inner"container and the outer shell around registering openings therein.

My improved construction consists in providing outwardly extending lugsill on the flanges d 25 formed around the open ends of the parts 2 andhot the inner container. These lugs it are provided at spaced points.The parts 2 and 3 of the inner container are secured together with theirflanges i in contact and with the lugs ill on each my part registeringand in contact with the lugs ii on the other part. The flanges i arethen secured to one another to form a fluid tight joint by welding orother similar suitable means, the

weld being made along a line near the base of the 35 flanges t andinwardly of the lugs ll 1|.

The outer shells t and ti may be provided at their open ends withoutwardly directed flanges Ii, if desired, or such flanges may beeliminated and the edges of the shells left straight as shown no in Fig.5;. The edges of the outer shells however are in any event provided withnotches l3 to fit around the outwardly extending lugs ii on the innercontainer, in order that the edges of the shells 5 and 6 between thelugs I [may be brought 45 into abutting contact with one another. Thenotches it are so proportioned as to bring the edges of the outer shellsat these points in abuttingrelation with the sides and edges of the lugsII on the inner shell. If desiiedi'the-notches I3 50 may be formedentirely in one ;of the outer shell parts 5 or 6 by making the shellpart which contains the notches slightly longer than the other shellpart.

The parts 5 and 6 of the outer shell are applied 55 to the innercontainer by placing them over opposite ends of the inner container andbringing edges of their open ends together in the region of the centralflange 4 on the inner container. The notches l3 in the edges of theouter shells permit the lugs II on the flanges of the inner container toproject to the exterior of the outer shell and also permits the edges ofthe outer shell between these notches to come into abutting contact withone another. When this assembly has been made, the edges of the outershells 5 and 6 are welded at the notches l3 to the ends of the outwardlyextending lugs l l on the inner container, which are welded together inthe same operation, and the abutting edges of the outer shells betweenthe notches I3 are welded to one another.

This provides a construction in which spaces are provided between theinner container and the outer shell between the lugs H in which heatinsulating material may be placed to more completely insulate the innercontainer from the outer shell, or a dead air space left for insulatingpurposes, the only heat conducting metal contact between the innercontainer and the outer shell in the region of joinder being through thespaced lugs ll.

Formal changes may be made in the specific embodiment of the inventiondescribed without departing from the spirit and substance of the broadinvention, the scope of which is commensurate with the appended claims.

I claim:

1. A metal barrel comprising a fluid container composed of a pair oflike parts each having a continuous outwardly extending flange at itsopen end, said flanges having spaced outwardly extending lug portionsand said flanges being welded to each other to provide a fluid tightjoint between said parts, an outer shell comprising two like partsadapted to flt over said inner container in spaced relation thereto andhaving their edges at their open ends abutting said lugs on the flangesof said inner container at a point spaced outwardly from the edges ofsaid flanges between said lugs, said edges of said outer shell parts andthe lugs on said flanges of said inner container all being securedtogether for securing said outer shell parts together and to said innercontainer.

2. A metal barrel comprising a fluid container composed of a pair orlike parts each having a open ends abutting said lugs on the flanges ofsaid inner container at a point spaced outwardly from the edges of saidflanges between said lugs, and said edges of said outer parts abuttingeach other between said lugs on said inner container, said edges of saidouter shell parts and the lugs on said flanges of said inner containerbeing secured together and the edges of said outer shell parts beingsecured together between said lugs, for securing said outer shell partstogether and to said inner container.

3. A metal barrel comprising a pair of pot shaped sections flanged intheir marginal edges and secured together through said flanges toprovide a closed inner container, circumferentially spaced projectionson said flanges, and a second pair of similarly shaped pot shapedmembers also flanged in their marginal edges, the flanges on said secondpair of pot shaped members-having mating recesses adapted to receive theprojections on said first mentioned flanges, said second pair of potshaped members being secured together through said flanges and securedto said projections, said second pair of pot shaped members beingrigidly retained in predetermined spaced relation to said first pair ofpot shaped members by said projections.

4. A metal barrel comprising a pair of pot shaped sections flanged intheir marginal edges and secured together through said flanges toprovide a closed liquid container, circumferentially spaced projectionson said flanges and a second pair of similar pot shaped members alsoflanged in their marginal edges and adapted to be secured together,recesses between the mating flanges of said second pair of pot shapedmembers adapted to receive said circumferentially spaced projectionswhereby said second pair of pot shaped members may be secured togetherand secured to said projections, said second pair of pot shaped membersbeing rigidly retained in predetermined spaced relation to said firstpair of pot shaped members by said projections.
